Two Brookline residents walking down Beacon Street in the Back Bay died when a driver ran a red light at Fairfield Street around 9:15 p.m., got into a crash with two other vehicles, rolled over, then hit them, according to WCVB and Boston Police.
John Lanzillotti, 28, of Brookline, who worked for the Red Sox, was declared dead at the scene. Jessica Campbell, 27, his girlfriend, was taken to Beth Israel Deaconess Medical Center, where she died.
Campbell, who described herself as a "retail analyst, social media geek, animal lover, yogi wannabe" on her Twitter feed, posted her last tweet about 45 minutes before the crash - a photo of yesterday's sunset over the Charles.
